President Trump has effectively handed Vladimir Putin an extraordinary green light: 50 days to finish off his brutal summer offensive in Ukraine before facing any consequences.

The US president says he is "disappointed" in Putin and will be sending "top-of-the-line" weapons to Ukraine, via Nato.

Trump also revealed that Putin had recently offered to assist in mediating between Israel and Iran during their brief June conflict — an offer he declined. “I said, ‘No, no, you help me get a settlement with you, with Russia,’” Trump recounted. “And I think we're going to be doing that too.”
